CEFB101-G

CEFB101-G is a 1A dual common-cathode fast switching rectangular Schottky barrier diode. It is one of the most commonly used diodes in rectifiers as it can efficiently convert alternating current (AC) to direct current (DC). The device is typically used as a protection diode for over-voltage and over-current protection, so it can be used in a wide range of applications including switch-mode power supplies and consumer electronics.The CEFB101-G utilizes a dual common-cathode configuration which allows for two rectified signals to be generated from one diode. The diode’s anode-cathode voltage, as well as the reverse switch-on voltage (Vr) are highly important characteristics to consider when selecting a device. The anode-cathode voltage, also known as the forward voltage drop, will influence the efficiency of the rectification process, while the reverse switch-on voltage will ensure that the voltage travels in the correct direction within the circuit. In order to enable fast switching, the CEFB101-G utilizes a Schottky barrier diode which allows greater current flow than a conventional PN junction diode. A Schottky diode offers unique characteristics including low forward voltages, low reverse leakage current, and high speed. This makes the CEFB101-G well suited for use as a rectifier in high frequency applications such as AC-DC converters, where fast switching times are required.The primary working principle of the CEFB101-G is the conversion of AC to DC. When AC is applied to the anode and cathode of the device, the forward voltage differential between the anode and the common-cathode cause current to flow from the anode to the cathode. This process is known as rectification, as it creates a DC output voltage at the common-cathode node.In order to ensure proper operation, it is important to conservatively select the forward and reverse voltages that the device can manage. As the CEFB101-G is designed to operate at a maximum of 1A, any application in which the voltage or the current is greater than this should utilize a more suitable device.In summary, the CEFB101-G is a dual common-cathode fast switching rectangular schottky barrier diode which offers excellent performance in rectifiers, and is typically used as a protection diode for over-voltage and over-current protection. The unique characteristics of the Schottky diode enable fast switching, making the device well suited for high frequency applications such as AC-DC converters. In order for the device to operate correctly, the forward and reverse voltages must be conservatively selected based on the maximum rated parameters of the diode.
